VVILLIAM H. DOANE, OF CINGINNATI, OHIO, ASSIGNOR TO HIMSELF AND J. A. FAY 8a OO., OF SAME PLAGE.

IMPROVED JOURNAL-BOX.

Specification forming part of Letters Patent No. 49,584, dated August 22, 1865.

To all 'whom t't may concern:

Be it known that I, WILLIAM H. DoANE, of Oincinnati,in the county of Hamilton and State of Ohio, have invented a new and Improved J ournal-Box; and I do hereby declare that the following is a full, clear,'aud exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a top view of the bottom half of the journal-box. Fig. 2 is a bottom view of the upper half of the box. Fi g. 3 is a vertical transverse section taken at the point indicated by red line w m in Figs. l and 2. Fig. 4 is a vertical transverse section through the box, taken at the point indicated by red line y y.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to certain improvements on journal-boxes which are termed selflubricating77 because there is employed in their construction a capillary substance for conducting the lubricating-oil from chambers beneath the journal to the surface of the latter, so as to keep it continually supplied with oil as long as any remains in said chambers.

The object of my invention is to so construct a journalbox Operating upon this principle thatit can be more conveniently cleaned of sand and viscous oil; also, to provide for conducting the pure oil from chambers at the extremities of the box to the middle of the length of the same by means of a capillary substance, and to provide for concluctin g the oil which escapes from the journal back again into said chambers, as will be hereinafter described.

To enable others skilled in the art to understand myinvention, I will describeits construction and operation.

lllyimprovedjournal-box consists of two sections, A and B. A is the lower section or bed7 and B is the upper section or cap, which is secured upon the bed by means of bolts a a a a.

The lower half of the journal-boxhas two rectangular chambers, b Z, at its ends, which are intended for containing oil for lubricat-ing the journal O, and which supply oil to the journal by means of a capillary substance of a suitable description introduced into the groove c, which extends along the bottom of the semicircular groove in this section A, as shown in Fig. 1. This groove c extends obliquely from one chamber b to the other, and may be as deep as the bottom of these chambers.

The bearing in the section A for the journal O is made of hardened metal by the well-known process of bushing, and, if desirable, ribs or beads a a may be cast on this bearing-surface for the purpose of entering annular grooves in the journal O and preventing end play thereof. On each side of the beariug for the journal O is a groove, c, which inclines toward the chambers b b, and which receives the oil escaping from thejournal and conducts it back into these chambers b. These longitudinal grooves or chambers e e are intended for preventing the oil which will escape from the journal G when it rotates very rapidly from insinuatin g itself between the two halves of the journal-box and escapin g therefrom.

The cap B of the journal-box is constructed with longitudinal channels c' e', communicating with the journal, and intended for allowing the superfiuous oil to escape freely from the journal into the grooves or channels c e, which conduct it back into the oil-chambers b b.

If desirable, a packing of any suitable substance may be introduced between the edges of the two halves of thejournal-box, as shown in Figs. 3 and 4; but this packingis not 'absolutely necessary to prevent the escape of the oil, as the grooves or Channels above nientioned will obviate this difficulty.

One great advantage of my improved journal-box over others is that I have a continuous slot extending lengthwise through the bearin g and communicating with oil-chambers at each end. Such slot being filled with cotton-wick or any other suitable capillary substance, it will supply oil uniformly to the journal; and when the oil in the box becoines thick it is only necessary to remove the cap B and journal O, when access can be had to every portion of the box to clean it.

The chambers b b may be supplied with oil at any time through the holes g gin the cap of the box. (Shown in Figs. 2 and 4.)

Having thus described my invention, what I claim as new, and desire to secure by Let- 3. `Providing fot` conducting the oil from the ters Patent, 18- journal G back into the chainbers b b at the ex- 1. A journal-box which is eonstructed with tremities of the journal-box, substantially as end ehambers, b b, and a channel 01' groove, c, l described. extendmg' lengthnzise through the box, sub- WILLIAM H DOAN stantiaily as desenbed.

2. The channeis e e, in combination with the Witnesses: end chambers, b Z), and Channels e' e' in the cap WILLIAM O. HARD, B, substantially as desoribed. J. T. DETWILER.
